5 Performance measured for 500GB product, using CrystalDiskMark (1000MB LBA range)
on SATA 6Gb/s host.
6 Power measured (all capacities) via MobileMark ™ 2014 @ 3.3V on SATA 6Gb/s host
(drive configured, DIPM enabled, HIPM disabled)
7 2TB capacity using JEDEC client workload (JESD219).
8 Operational temperature is defined as ambient temperature around the SSD. It is not
measured from the on-board temperature sensor. It is important to note that on-board
temperature sensor readings are expected to be higher than ambient temperature
when the SSD is placed inside a system.
